        <h2>Description</h2>
        <p>
      Generates random numbers with a user-defined limit and holds them for a period of time.

        <h2>Initialization</h2>
        <p>
      <span class="emphasis"><em>imode</em></span> (optional, default=0) -- generation mode of the
      first output value (see below)
    </p>
        <p>
      <span class="emphasis"><em>ifirstval</em></span> (optional, default=0) -- first output value

      </div>
      <div class="refsect1">
        <a id="idp141104656"></a>
        <h2>Performance</h2>
        <p>
      <span class="emphasis"><em>kmin</em></span> -- minimum range limit
    </p>
        <p>
      <span class="emphasis"><em>kmax</em></span> -- maximum range limit
    </p>
        <p>
      <span class="emphasis"><em>kcps, xcps</em></span> -- rate of random break-point generation
    </p>
        <p>
      The <span class="emphasis"><em>randomh</em></span> opcode is similar to <a class="link" href="randh.html" title="randh"><em class="citetitle">randh</em></a> but allows the user to set arbitrary minimum and maximum values.
    </p>
        <p>
      When <span class="emphasis"><em>imode</em></span> = 0 (the default), the <span class="emphasis"><em>kmin</em></span>
      argument value is outputted during <span class="emphasis"><em>1/kcps</em></span> (resp.
      <span class="emphasis"><em>1/xcps</em></span>) seconds at the beginning of the note. Then,
      the normal process takes place with a new random number generated and held
      every <span class="emphasis"><em>1/kcps</em></span> (resp. <span class="emphasis"><em>1/xcps</em></span>) seconds.
    </p>
        <p>
      When <span class="emphasis"><em>imode</em></span> = 2, the <span class="emphasis"><em>ifirstval</em></span>
      argument value is outputted during <span class="emphasis"><em>1/kcps</em></span> (resp.
      <span class="emphasis"><em>1/xcps</em></span>) seconds at the beginning of the note. Then,
      the normal process takes place with a new random number generated and held
      every <span class="emphasis"><em>1/kcps</em></span> (resp. <span class="emphasis"><em>1/xcps</em></span>) seconds.
    </p>
        <p>
      When <span class="emphasis"><em>imode</em></span> = 3, the generation process begins with a
      random value from the initialization time.
